AUTOMOBILE SG-NAL. 1

Apgiiangn 1inea April is, i922. semaine. 554,380.

Tljfe it known that I, EimesrI-Innn, a citi- 7 Zenf-offthefUnited,StatesVresiding .at Dubuq ue, in,the ,countyfof Dubuquefand State flown have i'nven'tednew 4and.useful Im- 'pioven'ients in Automobile Signals, ofwhich lthe following is a specification.

This ii'iventioni'elates to improvements `in `Signals and Ihas special relation to. direction ysignals forautomobiles.

l 'An v,object of :the kinvention is the provision of a signal offthe tabove y iharabter which `may be',convenientlyb operated vtogin-` H'dicat'e "a proposer A change in directionf-gor ,iiievmentof vehicle;

,"Anotlier object of the invention is the. `provision of 'a' direction signal ,which is novel in construction, :simple'and `efficient in operationv and wliichmay be readily se cured upgn a .vehicle in position for use.

'Withitheabove andother objects in view,

A the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the Vappended claims.

In the drawings Figure 1 is a side elevation of a portion of an automobile with the signal applied and shown in normal position.

. Figure 2is a top plan view of the subject matter of Figure 1 with the signal shown swung o-ut into signalling position by dotted lines.

Figure 3 is a section on the line 3-3 of Figure 2 with the signal extended in full lines.

Figure 4- is a fragmentary bottom plan view showing the outer end of thebracket and the adjacent portion of the signal arm.

Figure 5 is a section on the line 5 5 of Figure 2.

Figure 6 is a detail perspective view of the elbow cap.

Figure 7 is a detail sectional view taken on line 7-7 of Figure 6.

Referring in detail to the drawings, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a portion of an automobile, to which the signal is shown as applied.

The signal comprises a bracket of annular formation which includes an attaching arm 11 and a supporting arm 12, the former being provided with an elongated slot 13 for the passage of screws or bolts 14, by means of ,Which .the l .bracket may be adj A.se-

cured in position'. `4 The outerend of the arm 12.is providedwith an opening .15 `and po- ".sitioned within this opening one ,end ofV a 4tubular l elbow 16,the 'latter comprising a portion of a substantiallyL-,shaped signal arm17.v The elbow 16 isprovided .adjacent vone end with an annular iiange or collar `18 which yprovides ashoulder for engagement with the under face of the supportingarm 1,2.ofthe bracket. The adjacent end of the 4`elbow''is threaded and receives a threaded ,cap 19', `having an annular shoulder y2O whichengages lthe upper face of the sup- -porti-ng 12, so ,thatthe elbow 16; is

swivele'dwithin A,the l,opening 15 and the Y ,signal arinmounted for horizontalgswingmovement.

l 'flllieoute'r end of lthe signal arm ,liasse- `Cure/Cl thereto ,an electric lbulb 2,1 and ,this

bulb? the adjacent end of the signal arm 17 is received within a slot 22 provided in the signal member 23, the latter being shown in the formvof an arrow head. The signal member 23 is preferably colored red, while one half of the lamp 21, for example the half of the lamp which faces the rear of the automobile is colored red, while the opposite half is preferably colored green. The signal arm 17 is secured within the slot 22 through the medium of semi-circular iianged clamps 24, which are in turn secured to the adjacent side portions of the slot of the signal member 23.

The cap 19 of the elbow 16 carries a radially extending arm 25 and this arm is pivota-lly vsecured to one end of an operating rod or wire 26, which extends through an .elongated semiscircular casing 27, secured to the supporting arm 12. The wire or rod 26 preferably extends through the side of the vehicle and is provided with an operating knob or button 28.

In addition, the cap 19 carries spaced contact members 29, which are connected to the terminals of the lamp 21 by conductor wires 30, while carried by the supporting varm 17 and arranged in theV path of movement of the contacts 29 are statonary contacts 31. These last'mentioned contacts may be Vconnected by means of conductor wires 32 to a suitable source of current and the circuit thus formedy may be provided with a suitable controlling switch (not shown).

Normally, the signal 23 is arrangedsubstantially parallel with the vehicle ,Landmay be swung outward to an active or signalling position by a pull upon the operating ro or wire 26. This will rotate the inner end of the elbow 16 within the opening 15 and n bring the contacts 29 into engagement with the contacts 3l to close a circuit through the lamp. Movement of the lsignal in this directionsis limited by a stop 83, while a stop 34 limits the movement of the signal in an opposite direction.

The invention is susceptible of various changes in its form, proportions andv minor details lof construction and the right is Vherein reserved to make such changes as properly fall within the scope of the api pended claims.

Having described the invention what is'V claimed'k is:-

l'. An automobile signal of the character described `comprising a substantially L- shaped supporting bracket having its yvertical leg slotted 'and the horizontal leg apertured respectively, means provided for securing said vVertical leg through saidslot to the vehicle, an elongated semi-circular casing secured to the upper side of hori- Vzontal leg of Vsaid, bracket, an y L-shaped signal` larm having its` inner end `hanged ture. Y Y

vand threaded for insertion through the aperture in the horizontal leg of said bracket, a cap -threaded to said end on the upper siderof said bracket whereby a horizontal swinging movement is obtained, an arm radially extending from said cap and being substantially apertured, a rod extend- Ving through said semi-circularfcasing and van automobile body, an L-shaped swinging signalling arm having an upright portion. journaled and secured in the aperture of.

the support, a crank connected' withsaid disposed above the support 'andf a rod conf Vupright portion of the L-shaped arm and nected to said crank and adaptedto extend through a Wall of an automobile to the interior thereof. Y

In ytestimony whereof I myV signa-
